🦋 gpio_data_ro_bug(9) — Kernel API Manual, bestie edition 🦋

🌸 NAME 🌸

gpio_data_ro_bug — test if HW bug exists or not. That's the whole assignment, bestie: it's the little function that checks whether the hardware bug is there or not. Lowkey iconic. 💅

✨ SYNOPSIS ✨

okay so here's the exact signature, no cap:

int gpio_data_ro_bug (struct zynq_gpio *gpio );

🎀 ARGUMENTS 🎀

• gpio — Pointer to driver data struct. That's the whole argument: a pointer to the driver data struct. It's giving VIP pass to the function's whole situation. 🫶

💅 RETURN 💅

• 0 if bug doesnot exist.
• 1 if bug exists.

Yes, doesnot is literally in the original, and we are not ghosting that detail. 😭 Every character counts, fr fr.
